Question -

What are the different types of networking/internetworking devices ?

Answer -

In the smooth functioning of networks, many devices play important role. Here, in this section, we are going to discuss few of them.

$\sf\underline{{✇ \: MODEM :\: }{ \:}}$

A MODEM ( Modulator Demodulator ) is an electronic device that enables a computer to transmit data over telephone lines. It is device used to convert the digital signals into analog signals and vice versa. There are two types of MODEM — Internal Modem and External Modem.

$\sf\underline{{ ✇ \: HUB :\: }{ \: }}$

Hub is a hardware device used to connect several computer together. It contains multiple independent but connected modules of network. A hub is a device that provides a central connection point for cables from nodes, servers and peripherals. There are two types of Hubs — Active Hub and Passive Hub.

$\sf\underline{{ ✇ \: Switch :\: }{ \: }}$

A switch is a network device which is used to interconnect computers or devices on a network. It filters and forwards data packet across a network. It is also a multi-port device. It receives signals, cleans them and retransmits them. It is used in long network lines, which exceed the maximum rated distance for a single run.

$\sf\underline{{✇ \: Router : \: }{ \: }}$

A router is a communication device that is used to connect two different networks. It is used to forward data packets from the source machine to the destination machine by using the shortest path.

$\sf\underline{{ ✇ \: Bridge :\: }{ \: }}$

A network bridge is a computer networking device that creates a single aggregate network from multiple communication networks.

$\sf\underline{{✇ \: Gateway : \: }{ \: }}$

A gateway is a device that connects dissimilar networks. In Internet, several networks are communicating with each other and each network has a different configuration. In order to make a reliable communication among each other, there must be a device that helps in communicating that is Gateway.
